I have a '04 wagon so far I have added front and rear strut bars and 4 point lower control arm brace. I also put on 17 x 7.5 Rota tarmac w/ 225/45/17. The handles great, I just want alittle less body roll. I do'nt want to lower the car I want to just upgrage the sway bars and maybe endlinks. Should I just get the rear stock 20mm? Should I get front and rear? should I also get endlinks? Thanks for the info.
